Accretion disks in axially symmetric space-times — •Claus Lämmerzahl — ZARM, University of Bremen, Germany

For axially symmetric space-times we present the general analytic theory of thick accretion disks (Polish doughnts) based on an ideal fluid which also can be charged. Based on that, accretion disks can be constructed and can be characterized in terms of the effective gravitational potential, shape, mass density and pressure. First steps in order to extend this approach to viscous fluids are presented.
